"Economic Evaluation of Cycling Plants – An Approach to Show the Value of Operational Flexibility - presented at Power-Gen Europe 2006, Cologne

The changed market conditions have an influence on the operating profile of every power plant in order to be dispatched. Combined cycle power plants often do not strictly operate in a base loadlike regime running 8000 hours per year. Many units are operating in a daily start-stop regime with units starting up to two times a day. In this market environment, an economic model that incorporates only a certain amount of base load hours with fix power revenues will not describe the full picture, additional earnings from the above mentioned market opportunities would not be considered. To be more accurate, an extended approach for evaluating a cycling plant with high flexibility is necessary. Key parameters for operational flexibility are for example start-up time, standby operation and shut-down time. This paper describes an approach for evaluating flexibility for combined cycle cycling power plants."

ça n'a pas grand chose à voir avec "tout ou rien" - Simplement, toutes les centrales électriques classiques fonctionnent 24/7 - Les centrales turbines gaz sont extrêmement soupes, et peuvent êtres démarrées et arrêtées parfois plusieurs fois par jour.

centrale « tout ou rien »


Explanation:
Autrement dit, cette centrale est soit en service à pleine puissance, soit à l'arrêt. Il n'y a pas de situation intermédiaire.
Calqué sur le modèle ON-OFF s'appliquant à de nombreux appareils qui fonctionnent en mode TOUT OU RIEN.
